This is a result of exceeding your available Spending Limit. Your Spending Limit reflects the Typical Price of each product, so if you wanted to buy our Japanfusion Pure Transforming Cleanser for example, you would need at least $25 Spending Limit to add this to your basket. You then pay the Dynamic Member Price.
We have a few options if you'd like more spending limit, from upgrades, to top-ups! Please contact our Member Happiness team HERE and they can find the best solution for you.
